Which of the following information must be transcribed on the MAR?

The correct choice indicates that the Medication Administration Record (MAR) must include specific details about medication administration. This includes the dosage, route of administration, time the medication is to be given, the individual administering the medication, the medication name, and its strength.

Each of these elements is crucial for ensuring safe medication administration and tracking. The dosage and strength ensure that the correct amount of medication is given, while the route specifies how the medication is to be administered (e.g., orally, intravenously). The time of administration helps in adhering to the medication schedules, and noting who administered the medication adds a layer of accountability.

Including all these details on the MAR assists healthcare providers in monitoring the patient's medication regimen, preventing medication errors, and ensuring the overall safety of the treatment process. The other options, while containing relevant information, do not encompass all the key components that are specifically required on the MAR for effective medication management.
